It took a few pressure tests to get all the leaks taken care of, but it is now completed and leak free. Teflon thread tape is my new best friend! I decided to use a toggle switch and mount it next to my clutch start cancel. I just like toggles and it turned out nice and clean:

I was going to put the gauge there too, but it required too much cutting and I worried that it may cause problems down the line..... like breaking the plastic when I need to remove that panel. So, I decided to mount it in the rear near the compressor. It also saved me the trouble of routing all that air hose to the dash. I chose to put it in the jack compartment cover because if I ever decide to move it somewhere else, I can easily replace that part:

I mounted the tank on the rear cross member. I just had to cut off that little bracket in the middle of the bar and it fit perfectly:

For my hookups, I used a T fitting and ran two hoses along the frame rails and mounted the quick connect nipples in the hole in the gusset on my BudBuilt sliders:

Because I have a male nipple as the terminal of the hoses, I had to install a shut off valve on each side:

So far so good. It is working perfectly. I'm so stoked to be able to air down now!!!
 
Very nice, how much did that cost you? I've been looking at a viair system for airing down and later a train horn since people don't get the F*** out of my way when they are supposed to.
 
$450 from hornblasters.com

Thanks. I cant wait to finally be able to air down! I'd like to add a horn too.... and maybe a front locker.....maybe.
 
The male quick connect will handle dirt/mud/ice far better. The female quick connect will get covered and be tough to pull back.

Hey Toledo FJ,

That's a mighty fine looking installation. I don't mean to bust your bubble, but it looks like your condensation drain is near the top of the air tank. Is there a dip tube that goes to the bottom of the tank? if not you can't get rid of the moisture that the compressor puts into the tank each time it comes on. The air tank will eventully fill up and you will get water into your air guns, tires, etc.

Hope I'm wrong this time!

No, you are correct. The drain could only mount up in one location because of where I mounted the tank, and it isn't exactly in a good spot to drain anything. I wanted to put it on the bottom port on the passenger side of the tank, but then I couldn't connect the hose up to the other port because the frame is in the way. I'm working on a solution, but for now I guess i'll just periodically drain the tank. It is amazing how much water ends up in there! I'll let you know what I figure out. If worse comes to worse, I'll have to unhook the gauge line and put the drain fitting in there. Now that I know all the other connections are air tight, the gauge is not really necessary.
 
Just thought...how loud is that thing? I hear compressors are EXTREMELY loud.

Exactly. That is why.

Understandable. I put a white nylon caps over mine to keep mud/dirt out of them. The nylon holds up better than rubber did.

It is not loud at all. I can hardly hear it over the sound of the engine/exhaust. It does make the truck vibrate though. It's just an added bonus... vibrating seats :p I'm sure some are loud as hell, but this one (viair 480c) is really not bad at all. I was expecting it to be much louder.

I couldn't find a rubber for the female end. I just hook up a little female x female adapter and then I'm good to go. Where did you find a nylon cap to fit?

Whay is the CFM of the compressor?
 
Nice install!:cheers:

If your pressure switch is adjustable, I would turn it down. Can't think of any good use for 200psi on the trail and it's dangerous. A line blowing off, popping, etc is bad enough at 120-150, 200 would wake the dead!:eek: IIRC OSHA regs limit it to 150, preferably 120 due to the risks at higher pressure and it would be much easier on your pump.
 
I don't know if the switch is adjustable or not. The system is designed to operate at 200 PSI. I backed up all the connections with hose clamps, and I cranked the hell out of them. The system automatically kicks on when the tank pressure falls below 160 PSI. Viair - Your Vital Air Source.

Here are the CFM specs:

Viair - Your Vital Air Source.

I don't keep the tank under pressure all the time, and I don't always crank it to 200 PSI. I just took that pic when I was testing all the fittings for leaks so I wanted to pump it all the way.
 
Which valve? The ones just before the quick connect on the sliders? Yeah, everything is rated to 200 PSI.
 
No, the check valve is a "one-way" valve typically with a ball float type stop in it. It prevents backflow, so that when you reach the pressure-switch cutoff point there is not 200psi resting on the compression chamber once it stops running. You can install it inline anywhere between your compressor and the reservoir tank.

The first one I installed, I mounted right off the cylinder head and because of the heated air that typically comes out of a small compressor, it melted, or at least the ball float did. It was of inferior quality and was replaced by ExtremeAire for free with a HD check valve. I'd call them (talk to George) and order one. Theirs also has standard NPT threading.

Oh, ok... yes... everything is rated to 200 PSI. But like I said, I don't usually keep it under that much pressure.

I fixed the issue with the drain fitting very simply. I just ran another T fitting and connected the pressure switch and the gauge up to the same port on the tank. Then I moved the drain to the lowest spot on the tank as it is mounted. I just stuck a plug into the port where the drain was previously located. Now it can drain no problem!
 
Thanks again! I'll get some pics posted of the new hose configuration when I get back home. I'm visiting my brothers new baby in Boston until tuesday.
